Arthropods
Members of the phylum Arthropoda, composed of organisms having a hard, jointed exoskeleton and paired jointed legs. It includes the class INSECTS and the subclass ARACHNIDA, many species of which are important medically as parasites or as vectors of organisms capable of causing disease in man.
Arthropod Vectors
Arthropods, other than insects and arachnids, which transmit infective organisms from one host to another or from an inanimate reservoir to an animate host.
Spiders
Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (From Barnes, Invertebrate Zoology, 5th ed, p508; Smith, Insects and Other Arthropods of Medical Importance, 1973, pp424-430)
Crustacea
A large subphylum of mostly marine ARTHROPODS containing over 42,000 species. They include familiar arthropods such as lobsters (NEPHROPIDAE), crabs (BRACHYURA), shrimp (PENAEIDAE), and barnacles (THORACICA).
Arachnida
A class of Arthropoda that includes SPIDERS; TICKS; MITES; and SCORPIONS.
Wolbachia
A genus of bacteria comprised of a heterogenous group of gram-negative small rods and coccoid forms associated with arthropods. (From Bergey's Manual of Systematic Bacteriology, vol 1, 1984)
Phylogeny
The relationships of groups of organisms as reflected by their genetic makeup.
Insects
The class Insecta, in the phylum ARTHROPODA, whose members are characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth; several hundred thousand different kinds having been described. Three orders, HEMIPTERA; DIPTERA; and SIPHONAPTERA; are of medical interest in that they cause disease in humans and animals. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p1)
Arthropod Proteins
Proteins synthesized by organisms belonging to the phylum ARTHROPODA. Included in this heading are proteins from the subdivisions ARACHNIDA; CRUSTACEA; and HORSESHOE CRABS. Note that a separate heading for INSECT PROTEINS is listed under this heading.
Arthropod Venoms
Venoms from animals of the phylum Arthropoda. Those most investigated are from scorpions and spiders of the class Arachnidae and from ant, bee, and wasp families of the Insecta order Hymenoptera. The venoms contain protein toxins, enzymes, and other bioactive substances and may be lethal to man.

Scorpions
Arthropods of the order Scorpiones, of which 1500 to 2000 species have been described. The most common live in tropical or subtropical areas. They are nocturnal and feed principally on insects and other arthropods. They are large arachnids but do not attack man spontaneously. They have a venomous sting. Their medical significance varies considerably and is dependent on their habits and venom potency rather than on their size. At most, the sting is equivalent to that of a hornet but certain species possess a highly toxic venom potentially fatal to humans. (From Dorland, 27th ed; Smith, Insects and Other Arthropods of Medical Importance, 1973, p417; Barnes, Invertebrate Zoology, 5th ed, p503)

Tribolium
A genus of small beetles of the family Tenebrionidae; T. confusum is the "confused flour beetle".
Beetles
INSECTS of the order Coleoptera, containing over 350,000 species in 150 families. They possess hard bodies and their mouthparts are adapted for chewing.
Isopoda
One of the largest orders of mostly marine CRUSTACEA, containing over 10,000 species. Like AMPHIPODA, the other large order in the superorder Peracarida, members are shrimp-like in appearance, have sessile compound eyes, and no carapace. But unlike Amphipoda, they possess abdominal pleopods (modified as gills) and their bodies are dorsoventrally flattened.

They penetrate the skin of their host by means of highly specialized, hooked mouth parts and feed on its blood. Ticks attack all groups of terrestrial vertebrates. In humans they are responsible for many TICK-BORNE DISEASES, including the transmission of ROCKY MOUNTAIN SPOTTED FEVER; TULAREMIA; BABESIOSIS; AFRICAN SWINE FEVER; and RELAPSING FEVER. (From Barnes, Invertebrate Zoology, 5th ed, pp543-44)
Tetranychidae
Family of spider MITES, in the superfamily Tetranychoidea, suborder Trombidiformes.
Mites
Any arthropod of the subclass ACARI except the TICKS. They are minute animals related to the spiders, usually having transparent or semitransparent bodies. They may be parasitic on humans and domestic animals, producing various irritations of the skin (MITE INFESTATIONS). Many mite species are important to human and veterinary medicine as both parasite and vector. Mites also infest plants.

Molting
Periodic casting off FEATHERS; HAIR; or cuticle. Molting is a process of sloughing or desquamation, especially the shedding of an outer covering and the development of a new one. This phenomenon permits growth in ARTHROPODS, skin renewal in AMPHIBIANS and REPTILES, and the shedding of winter coats in BIRDS and MAMMALS.
Horseshoe Crabs
An arthropod subclass (Xiphosura) comprising the North American (Limulus) and Asiatic (Tachypleus) genera of horseshoe crabs.

Herbivory
The act of feeding on plants by animals.
Diptera
An order of the class Insecta. Wings, when present, number two and distinguish Diptera from other so-called flies, while the halteres, or reduced hindwings, separate Diptera from other insects with one pair of wings. The order includes the families Calliphoridae, Oestridae, Phoridae, SARCOPHAGIDAE, Scatophagidae, Sciaridae, SIMULIIDAE, Tabanidae, Therevidae, Trypetidae, CERATOPOGONIDAE; CHIRONOMIDAE; CULICIDAE; DROSOPHILIDAE; GLOSSINIDAE; MUSCIDAE; TEPHRITIDAE; and PSYCHODIDAE.

Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)

Myths, models and mitigation of resistance to pesticides. (1/594)

Resistance to pesticides in arthropod pests is a significant economic, ecological and public health problem. Although extensive research has been conducted on diverse aspects of pesticide resistance and we have learned a great deal during the past 50 years, to some degree the discussion about 'resistance management' has been based on 'myths'. One myth involves the belief that we can manage resistance. I will maintain that we can only attempt to mitigate resistance because resistance is a natural evolutionary response to environmental stresses. As such, resistance will remain an ongoing dilemma in pest management and we can only delay the onset of resistance to pesticides. 'Resistance management' models and tactics have been much discussed but have been tested and deployed in practical pest management programmes with only limited success. Yet the myth persists that better models will provide a 'solution' to the problem. The reality is that success in using mitigation models is limited because these models are applied to inappropriate situations in which the critical genetic, ecological, biological or logistic assumptions cannot be met. It is difficult to predict in advance which model is appropriate to a particular situation; if the model assumptions cannot be met, applying the model sometimes can increase the rate of resistance development rather than slow it down. Are there any solutions? I believe we already have one. Unfortunately, it is not a simple or easy one to deploy. It involves employing effective agronomic practices to develop and maintain a healthy crop, monitoring pest densities, evaluating economic injury levels so that pesticides are applied only when necessary, deploying and conserving biological control agents, using host-plant resistance, cultural controls of the pest, biorational pest controls, and genetic control methods. As a part of a truly multi-tactic strategy, it is crucial to evaluate the effect of pesticides on natural enemies in order to preserve them in the cropping system. Sometimes, pesticide-resistant natural enemies are effective components of this resistance mitigation programme. Another name for this resistance mitigation model is integrated pest management (IPM). This complex model was outlined in some detail nearly 40 years ago by V. M. Stern and colleagues. To deploy the IPM resistance mitigation model, we must admit that pest management and resistance mitigation programmes are not sustainable if based on a single-tactic strategy. Delaying resistance, whether to traditional pesticides or to transgenic plants containing toxin genes from Bacillus thuringiensis, will require that we develop multi-tactic pest management programmes that incorporate all appropriate pest management approaches. Because pesticides are limited resources, and their loss can result in significant social and economic costs, they should be reserved for situations where they are truly needed--as tools to subdue an unexpected pest population outbreak. Effective multi-tactic IPM programmes delay resistance (= mitigation) because the number and rates of pesticide applications will be reduced.  (+info)

Hemocyanin of the horseshoe crab, Limulus polyphemus. Structural differentiation of the isolated components. (2/594)

The high molecular weight hemocyanin found in the hemolymph of the horseshoe crab, Limulus polyphemus, is composed of at least eight different kinds of subunits. Ion exchange chromatography at high pH in the presence of EDTA yields five major zones, hemocyanins I to V, three of which are electrophoretically heterogeneous. The subunits have similar molecular weights, 65,000 to 70,000, and their amino acid compositions are remarkably similar to each other and to other arthropod and molluscan hemocyanins. Digestion of the native subunits of Limulus hemocyanin by formic acid or trypsin shows considerable structural diversity which is supported by cyanogen bromide cleavage patterns and by peptide mapping of the tryptic peptides prepared from denatured hemocyanin subunits. The structural differentiation of the subunits is accompanied by functional differentiation, as shown in previous investigations of their O2 and CO affinities (Sullivan, B., Bonaventura, J., and Bonaventura, C. (1974) Proc. Natl. Acad. Sci. U.S.A. 71, 2558-2562; Bonaventura, C., Bonaventura, J., Sullivan, B., and Bourne, S. (1975) Biochemistry 13, 4784-4789). The subunit diversity of Limulus hemocyanin suggests that other electrophoretically heterogeneous hemocyanins may be composed of structurally distinct subunits.  (+info)

Cryptocyanin, a crustacean molting protein: evolutionary link with arthropod hemocyanins and insect hexamerins. (3/594)

Cryptocyanin, a copper-free hexameric protein in crab (Cancer magister) hemolymph, has been characterized and the amino acid sequence has been deduced from its cDNA. It is markedly similar in sequence, size, and structure to hemocyanin, the copper-containing oxygen-transport protein found in many arthropods. Cryptocyanin does not bind oxygen, however, and lacks three of the six highly conserved copper-binding histidine residues of hemocyanin. Cryptocyanin has no phenoloxidase activity, although a phenoloxidase is present in the hemolymph. The concentration of cryptocyanin in the hemolymph is closely coordinated with the molt cycle and reaches levels higher than hemocyanin during premolt. Cryptocyanin resembles insect hexamerins in the lack of copper, molt cycle patterns of biosynthesis, and potential contributions to the new exoskeleton. Phylogenetic analysis of sequence similarities between cryptocyanin and other members of the hemocyanin gene family shows that cryptocyanin is closely associated with crustacean hemocyanins and suggests that cryptocyanin arose as a result of a hemocyanin gene duplication. The presence of both hemocyanin and cryptocyanin in one animal provides an example of how insect hexamerins might have evolved from hemocyanin. Our results suggest that multiple members of the hemocyanin gene family-hemocyanin, cryptocyanin, phenoloxidase, and hexamerins-may participate in two vital functions of molting animals, oxygen binding and molting. Cryptocyanin may provide important molecular data to further investigate evolutionary relationships among all molting animals.  (+info)

Mechanisms of arthropod transmission of plant and animal viruses. (4/594)

A majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. The viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. A majority of plant viruses are carried on the cuticle lining of a vector's mouthparts or foregut. This initially appeared to be simple mechanical contamination, but it is now known to be a biologically complex interaction between specific virus proteins and as yet unidentified vector cuticle-associated compounds. Numerous other plant viruses and the majority of animal viruses are carried within the body of the vector. These viruses have evolved specific mechanisms to enable them to be transported through multiple tissues and to evade vector defenses. In response, vector species have evolved so that not all individuals within a species are susceptible to virus infection or can serve as a competent vector. Not only are the virus components of the transmission process being identified, but also the genetic and physiological components of the vectors which determine their ability to be used successfully by the virus are being elucidated. The mechanisms of arthropod-virus associations are many and complex, but common themes are beginning to emerge which may allow the development of novel strategies to ultimately control epidemics caused by arthropod-borne viruses.  (+info)

Internal phylogeny of the Chilopoda (Myriapoda, Arthropoda) using complete 18S rDNA and partial 28S rDNA sequences. (5/594)

The internal phylogeny of the 'myriapod' class Chilopoda is evaluated for 12 species belonging to the five extant centipede orders, using 18S rDNA complete gene sequence and 28S rDNA partial gene sequence data. Equally and differentially weighted parsimony, neighbour-joining and maximum-likelihood were used for phylogenetic reconstruction, and bootstrapping and branch support analyses were performed to evaluate tree topology stability. The results show that the Chilopoda constitute a monophyletic group that is divided into two lines, Notostigmophora (= Scutigeromorpha) and Pleurostigmophora, as found in previous morphological analyses. The Notostigmophora are markedly modified for their epigenic mode of life. The first offshoot of the Pleurostigmophora are the Lithobiomorpha, followed by the Craterostigmomorpha and by the Epimorpha s. str. (= Scolopendromorpha + Geophilomorpha), although strong support for the monophyly of the Epimorpha s. lat. (= Craterostigmomorpha + Epimorpha s. str.) is only found in the differentially weighted parsimony analysis.  (+info)

Divergence time estimates for the early history of animal phyla and the origin of plants, animals and fungi. (6/594)

In the past, molecular clocks have been used to estimate divergence times among animal phyla, but those time estimates have varied widely (1200-670 million years ago, Ma). In order to obtain time estimates that are more robust, we have analysed a larger number of genes for divergences among three well-represented animal phyla, and among plants, animals and fungi. The time estimate for the chordate-arthropod divergence, using 50 genes, is 993 +/- 46 Ma. Nematodes were found to have diverged from the lineage leading to arthropods and chordates at 1177 +/- 79 Ma. Phylogenetic analyses also show that a basal position of nematodes has strong support (p > 99%) and is not the result of rate biases. The three-way split (relationships unresolved) of plants, animals and fungi was estimated at 1576 +/- 88 Ma. By inference, the basal animal phyla (Porifera, Cnidaria, Ctenophora) diverged between about 1200-1500 Ma. This suggests that at least six animal phyla originated deep in the Precambrian, more than 400 million years earlier than their first appearance in the fossil record.  (+info)

Animal mitochondrial genomes. (7/594)

Animal mitochondrial DNA is a small, extrachromosomal genome, typically approximately 16 kb in size. With few exceptions, all animal mitochondrial genomes contain the same 37 genes: two for rRNAs, 13 for proteins and 22 for tRNAs. The products of these genes, along with RNAs and proteins imported from the cytoplasm, endow mitochondria with their own systems for DNA replication, transcription, mRNA processing and translation of proteins. The study of these genomes as they function in mitochondrial systems-'mitochondrial genomics'-serves as a model for genome evolution. Furthermore, the comparison of animal mitochondrial gene arrangements has become a very powerful means for inferring ancient evolutionary relationships, since rearrangements appear to be unique, generally rare events that are unlikely to arise independently in separate evolutionary lineages. Complete mitochondrial gene arrangements have been published for 58 chordate species and 29 non-chordate species, and partial arrangements for hundreds of other taxa. This review compares and summarizes these gene arrangements and points out some of the questions that may be addressed by comparing mitochondrial systems.  (+info)

Molecular characterization of American cockroach tropomyosin (Periplaneta americana allergen 7), a cross-reactive allergen. (8/594)

Inhalation of allergens produced by the American cockroach (Periplaneta americana) induces IgE Ab production and the development of asthma in genetically predisposed individuals. The cloning and expression in Escherichia coli of P. americana tropomyosin allergen have been achieved. The protein shares high homology with other arthropod tropomyosins (80% identity) but less homology with vertebrate ones (50% identity). The recombinant allergen was produced in E. coli as a nonfusion protein with a yield of 9 mg/l of bacterial culture. Both natural and recombinant tropomyosins were purified by isoelectric precipitation. P. americana allergen 1 (Per a 1) and Per a 7 (tropomyosin) are to date the only cross-reacting allergens found in cockroaches. ELISA and Western blot inhibition experiments, using natural and recombinant purified tropomyosins from shrimp and cockroach, showed that tropomyosin induced cross-reactivity of IgE from patients allergic to these allergens, suggesting that this molecule could be a common allergen among invertebrates.  (+info)

BACKGROUND: The ancient and diverse, yet understudied arthropod class Diplopoda, the millipedes, has a muddled taxonomic history. Despite having a cosmopolitan distribution and a number of unique and interesting characteristics, the group has received relatively little attention; interest in millipede systematics is low compared to taxa of comparable diversity. The existing classification of the group comprises 16 orders. Past attempts to reconstruct millipede phylogenies have suffered from a paucity of characters and included too few taxa to confidently resolve relationships and make formal nomenclatural changes. Herein, we reconstruct an ordinal-level phylogeny for the class Diplopoda using the largest character set ever assembled for the group. METHODS: Transcriptomic sequences were obtained from exemplar taxa representing much of the diversity of millipede orders using second-generation (i.e., next-generation or high-throughput) sequencing. These data were subject to rigorous orthology ...

With over 1 million living species described and a rich 520 Myr fossil record, arthropods are the most species-rich clade of animals on Earth, accounting for nearly 80 per cent of animal biodiversity [1]. Four main euarthropod sub-phyla are recognized: Hexapoda (including insects); Crustacea (lobsters, water fleas and others); Myriapoda (e.g. millipedes and centipedes); and Chelicerata (including arachnids, horseshoe crabs and possibly sea spiders). After many years of debate, a consensus has emerged that these four classes (or sub-phyla) form a monophyletic group called the Euarthropoda [2,3]. The relationships between the four euarthropod groups remain disputed, however, as is the validity of their close relationship to tardigrades (water bears) and onychophorans (velvet worms) in a more inclusive clade called Arthropoda (named Panarthropoda by Nielsen [4]).. Within the Euarthropoda, the main point of disagreement concerns the position of the myriapods, which were long thought to be most ...

Yellow-spotted Millipede. The yellow-spotted millipede is a species of arthropod in the Myriapoda, the many-legged ones a group that also includes centipedes. Myriapods possess from fewer than 10 to nearly 200 pairs of appendages (legs). They often occur in moist climates like that of the Pacific. Northwest; they may be found in damp places under stones and logs, in leaf litter, or soil. Millipedes play an important ecological role in converting forest floor litter into fertile topsoil.. At certain times of the year forested trails within RNSP are literally crawling with yellow-spotted millipedes and their nymphs, which hatch small and white and take approximately two years and several molts of their exoskeleton to reach maturity. Millipedes belong to the arthropod class Diplopoda, which means double legs, they have two pairs of legs per body segment. Yellow-spotted millipedes have 18-20 body segments and 31 pairs of legs (not a thousand like the name millipede suggests). The cylindrical ...

Blobology analysis revealed 13 contigs with deviating GC content, which could be the result of contamination. The GC content in scaffold 160 was only 29.9%. Blast searches in the NCBI non-redundant database yielded no significant hits to non-metazoan sequences for this scaffold, suggesting that this scaffold is not a result of contamination. Instead, visual inspection revealed stretches of low base pair calling. (N stretches) along this scaffold, which resulted in a biased GC estimate. The remaining 12 scaffolds show GC contents of approximately 50%.

The use of directional traps for the assessment of short-term phenanthrene effects upon soil springtail communities. : In: Environmental Pollution, 2006, 140 (2), pp.364-370. Directional traps, both horizontal and vertical, were used to assess the behavioural impact of phenanthrene application on soil springtail communities. Avoidance was not detected. Rather, a vertical attraction of the dominant species, Folsomia manolachei, was demonstrated, as well as a decrease in horizontal movements of Lepidocyrtus

Myriapoda - Simple English Wikipedia, the free encyclopediaMyriapoda - Simple English Wikipedia, the free encyclopedia
Millipedes are the class Diplopoda, where most segments appear to have two pairs of legs. This happened because each pair of body segments fused (joined) into a single unit, which gives them the appearance of having two pairs of legs per segment. They are slower than centipedes, and feed on leaf litter and detritus. Around 8,000 species have been described, which may represent less than a tenth of the true global millipede diversity.[6] One species, Illacme plenipes has the greatest number of legs of any animal, with 750.[2] Millipedes typically have between 36 and 400 legs. Pill millipedes are much shorter, and are capable of rolling up into a ball, like pillbugs. ...

Enalikter: not arthropod but annelid | Proceedings of the Royal Society of London B: Biological SciencesEnalikter: not arthropod but annelid | Proceedings of the Royal Society of London B: Biological Sciences
Siveter et al. [1] recently described a new putative megacheiran arthropod, Enalikter aphson, from the Silurian Herefordshire Lagerstätte and discussed its impact on arthropod phylogeny and the survival of megacheirans beyond the Cambrian Period.. In this comment, we should like to suggest an alternative interpretation of the new fossil. We think that the evidence for arthropod affinities of E. aphson is not compelling, and we argue that all features of this species are more compatible with an annelid affinity of E. aphson. Accordingly, the supposed impact of E. aphson on arthropod phylogeny and longevity of early megacheirans is questioned.. The body of E. aphson is composed of segments that bear appendages, some of which are interpreted as biramous or multiramous. The segments lack a well-delineated tergite on the dorsal side; as pointed out by Siveter et al. [1] tergo-pleurae are also not visible in the material. Siveter et al.

A Fascinating Creature. Petroglyph National Monument is unique in many ways, but one of its most striking attributes is the seventeen-mile long volcanic escarpment. In addition to having thousands of petroglyphs on the basalt boulders, the escarpment is home to many plants and animals that may not usually be found this far north in the Chihuahuan Desert. The boulders strewn across the escarpment allow moisture and heat to be concentrated. This gives plants and animals the slight edge they need to be able to survive. One such animal is the millipede. Millipedes are known to exist in many different habitats from rainforests to sub-alpine mountaintops to deserts. The millipedes that live in these diverse habitats have adapted in order to survive the elements. Some have developed mechanisms to keep from freezing, to keep from being eaten or to keep from drying out in the heat. In whatever habitat they occupy, millipedes are fascinating creatures that have a long history and are an important member ...

The Rockies are so magnificently beautiful its hard to imagine that there could be even more awesome experiences there than gazing at those mountains and lakes. But if you make it to Lake Louise, Alberta, take the time to travel another 30 kilometers to a World Heritage site that is awesome in the original sense of the word. It is well worth the drive and an overnight stay to take the guided hike the next day to the Burgess Shale, located in Yoho National Park on the British Columbia side of the Rockies..

In the course of exploratory field studies on arthropods with defensive glands, we came across two species which emit a strong and persistent phenolic odor when handled. One is a carabid beetle |em|(Chlaenius cordicollis Kirby)|/em|, the other a chordeumoid millipede [|em|Abacion magnum|/em| (Loomis)]. The fact that both animals produce repellent secretions is not surprising, since many other carabids and millipedes are well known for their defensive glands. But the particular phenolic odor possessed by these two species is unIike the odor of any other arthropod secretion that has been studied (for a summary of defensive secretions of arthropods see Roth and Eisner, 1962).The purpose of this paper is to report on the nature of the two phenols involved, and to discuss the structure and mode of operation of the glands, as well as their defensive effectiveness. Both species were collected in the environs of Ithaca, N. Y. |em|Abacion|/em| was from leaf litter in deciduous woods, and |em|Chlaenius|/em| from

Any way you look at it - by sheer weight, species diversity or population - the hard-shelled, joint-legged creepy crawlies called arthropods dominate planet Earth. Because of their success and importance, scientists have been trying for decades to figure out the family relationships that link lobsters to millipedes and cockroaches to tarantulas and find which might have come first.. In a scientific and technological tour de force that was nearly a decade in the making, a team of scientists from Duke University, the University of Maryland and the Natural History Museum of Los Angeles County have compared genetic sequences from 75 different species to draw a new family tree that includes every major arthropod lineage. Some of the relationships are so surprising that new names had to be coined for five newly-discovered groupings.. The work, which was supported by the National Science Foundation, appears early online Wednesday in the journal Nature.. A big surprise to tumble out of the new tree is ...

Nonnative plant shifts functional groups of arthropods following droughtNonnative plant shifts functional groups of arthropods following drought
Nonnative plants alter the composition of native plant communities, with concomitant effects on arthropods. However, plant invasions may not be the only disturbance affecting native communities, and multiple disturbances can have compounding effects. We assessed the effects of invasion and drought on plant and arthropod communities by comparing grasslands dominated by nonnative Old World bluestem grasses (OWBs, Dichanthium annulatum) to grasslands dominated by native plants during a period of decreasing drought severity (2011â€2013). Native plant communities had more species of plants and arthropods (/m2) than areas dominated by OWBs during extreme drought, but richness was comparable as drought severity decreased. Abundance of arthropods was greater in native plant communities than in OWB communities during extreme drought, but OWB communities had more arthropods during moderate and non-drought conditions. We observed a shift in the arthropod community from one dominated by detritivores to ...

How to Get Rid of Springtails - How to Get Rid of Stuff
We have been inundated with springtails (verified by our county vector control entomologist) for almost 3 months since getting 4 new sliding doors installed. Showers, essential oil baths, washing all linens and vacuuming mattresses and floors every day have kept them down. We have had terminex spray inside 4x and outside 3x, which helps temporarily. Our outdoor sprinklers were leaking and we ripped up and replaced the sprinklers and front yard - new topsoil and sod. They die from flea powder for the carpet, but come back within a week. We are having some plants with whiteflies torn out, and removing all mulch. Diatamaceous earth work pretty well, as it compromises their joints and dries them out. There is a company called Diatect that sells an organic product with food-grade D.E. and natural pyrethrens from african daisies.

A natural history of conspecific aggregations in terrestrial arthropods, with emphasis on cycloalexy in leaf beetles ...A natural history of conspecific aggregations in terrestrial arthropods, with emphasis on cycloalexy in leaf beetles ...
Aggregations of conspecifics are ubiquitous in the biological world. In arthropods, such aggregations are generated and regulated through complex interactions of chemical and mechanical as well as abiotic and biotic factors. Aggregations are often functionally associated with facilitation of defense, thermomodulation, feeding, and reproduction, amongst others. Although the iconic aggregations of locusts, fireflies, and monarch butterflies come to mind, many other groups of arthropods also aggregate. Cycloalexy is a form of circular or quasicircular aggregation found in many animals. In terrestrial arthropods, cycloalexy appears to be a form of defensive aggregation although we cannot rule out other functions, particularly thermomodulation. In insects, cycloalexic-associated behaviors may include coordinated movements, such as the adoption of seemingly threatening postures, regurgitation of presumably toxic compounds, as well as biting movements. These behaviors appear to be associated with attempts to

Ecosystem engineering is a process by which organisms change the distribution of resources and create new habitats for other species via non-trophic interactions. Leaf-rolling caterpillars can act as ecosystem engineers because they provide shelter to secondary users. In this study, we report the influence of leaf-rolling caterpillars on speciose tropical arthropod communities along both spatial scales (leaf-level and plant-level effects) and temporal scales (dry and rainy seasons). We predict that rolled leaves can amplify arthropod diversity at both the leaf and plant levels and that this effect is stronger in dry seasons, when arthropods are prone to desiccation. Our results show that the abundance, richness, and biomass of arthropods within several guilds increased up to 22-fold in naturally and artificially created leaf shelters relative to unaltered leaves. These effects were observed at similar magnitudes at both the leaf and plant scales. Variation in the shelter architecture (funnel, ...

Memoirs: On the Antennal Musculature in Insects and other Arthropods | Journal of Cell ScienceMemoirs: On the Antennal Musculature in Insects and other Arthropods | Journal of Cell Science
The first antennae of arthropods are divisible into two main types, viz. (1) segmented antennae and (2) annulated antennae. In the first type the antenna consists of a variable number of segments, each having intrinsic musculature. The antennae of the Ohilopoda, Diplopoda, Pauropoda, Symphyla, Collembola, and Thysanura Entognatha all pertain to this type; also, the first antennae of many Copepoda and Ostracoda.. In the second type the antenna consists of a peduncle or protopodite composed of one or more segments, each with intrinsic musculature. Distally it bears an annulated flagellum, or a pair of flagella, devoid of intrinsic muscles and whose movements are effected by muscles originating within the peduncle. The first antennae of the Crustacea Malacostraca and the antennae of the Thysanura Ectognatha and of all the Insecta Pterygota belong to this type.. The greatly elongated antennae of the Schizotarsia are intermediate between these two types. They are composed of an immense number of ...

Although molecular analyses have contributed to a better resolution of the animal tree of life, the phylogenetic position of tardigrades (water bears) is still controversial, as they have been united alternatively with nematodes, arthropods, onychophorans (velvet worms), or onychophorans plus arthropods. Depending on the hypothesis favoured, segmental ganglia in tardigrades and arthropods might either have evolved independently, or they might well be homologous, suggesting that they were either lost in onychophorans or are a synapomorphy of tardigrades and arthropods. To evaluate these alternatives, we analysed the organisation of the nervous system in three tardigrade species using antisera directed against tyrosinated and acetylated tubulin, the amine transmitter serotonin, and the invertebrate neuropeptides FMRFamide, allatostatin and perisulfakinin. In addition, we performed retrograde staining of nerves in the onychophoran Euperipatoides rowelli in order to compare the serial locations of motor

In Drosophila, the T-box genes optomotor-blind (omb) and H15 have been implicated in specifying the development of the dorso-ventral (DV) axis of the appendages. Results from the spider Cupiennius salei have suggested that this DV patterning system may be at least partially conserved. Here we extend the study of the DV patterning genes omb and H15 to a representative of the Myriapoda in order to add to the existing comparative data set and to gain further insight into the evolution of the DV patterning system in arthropod appendages. The omb gene of the millipede Glomeris marginata is expressed on the dorsal side of all appendages including trunk legs, maxillae, mandibles, and antennae. This is similar to what is known from Drosophila and Cupiennius and suggests that the role of omb in instructing dorsal fates is conserved in arthropods. Interestingly, the lobe-shaped portions of the mouthparts do not express omb, indicating that these are ventral components and thus may be homologous to the ...

The super worm (Zophobas morio) is a larva of a species of darkling beetle. Only the larvae are fed out to amphibians, as the adult are not preferred foods for frogs. This insect goes through complete metamorphosis.. We also have a colony of earthworms. Our colonies are not thriving at the moment, so most of the time we harvest from our own backyard. The other food item that we are currently not breeding, but do feed out, is the Neoconocephalus saturatus, a type of cone-headed katydid. We rely on a local family to help us out by collecting these katydids for us.. Last, but certainly not least, is the newest food item on the menu at EVACC; Blaberus discoidalis, a very large cockroach.. ...

Dating tardigrade evolution and early terrestrialization events.Dating tardigrade evolution and early terrestrialization events.
The tempo and mode of cryptobiosis evolution within tardigrades are still unknown, but it is clear that comprehending this process is the key to better understand evolutionary history and ecology of this phylum, and the process of animal terrestrialization, given the ubiquitous continental distribution of tardigrades. Our study was mainly aimed at timing tardigrade radiation and key events in tardigrade evolution. Given the existence of two lineages of continental tardigrades, i.e. Eutardigrada and Echiniscidae, we decided to implement a relaxed molecular clock based approach to attempt to derive a minimal time interval for tardigrade terrestrialization. Data from new and Genbank partial 18S and 28S rDNA sequences of 41 specimens, belonging to 31 species from 26 genera, representing all known tardigrade orders and superfamilies, were acquired. Phylogenetic inference was achieved using Bayesian mixture models that have allowed the most accurate estimates of evolutionary rates. The following ...

Venomous animals have evolved with sophisticated bio-chemical strategies to arrest prey and defend themselves from natural predators. In recent years, peptide toxins from venomous animals have drawn considerable attention from researchers due to their surprising chemical, biochemical, and pharmacological diversity. Similar to other venomous animals, centipedes are one of the crucial venomous arthropods that have been used in traditional medicine for hundreds of years in China. Despite signifying pharmacological importance, very little is known about the active components of centipede venoms. More than 500 peptide sequences have been reported in centipede venomous glands by transcriptome analysis, but only a small number of peptide toxins from centipede has been functionally described. Like other venomous animals such as snakes, scorpions, and spiders, the venom of centipedes could be an excellent source of peptides for developing drugs for treatments as well as bio-insecticides for agrochemical

Phylogeny of the genus Pseudosinella (Hexapoda, Collembola) from the Western Carpathians caves reveals Miocene diversificationPhylogeny of the genus Pseudosinella (Hexapoda, Collembola) from the Western Carpathians caves reveals Miocene diversification
The observations from the recent period revealed that the Western Carpathians, a part of the Carpathian mountain chain, is the northernmost region in Europe with the occurrence of the obligate cave fauna. The collembolan genus Pseudosinella Schäffer, 1897 is a polyphyletic taxon derived from the genus Lepidocyrtus Bourlet, 1839 from which it differs in reduced number of eyes. It covers about 350 species with predominantly Holarctic distribution of which about 39% are confined to caves. We studied the morphology and molecular traits to identify cave species of the genus Pseudosinella occupying the Western Carpathian caves and clarify their phylogenetic relationships. Based on morphological traits we hypothesized that Pseudosinella aggtelekiensis (Stach, 1929) and P. paclti Rusek, 1961 are descendants of the different phyletic lineages, the former species lacking morphologically related edaphic species. On the other hand, several species related to P. paclti were found in caves, superficial subterranean

Isolation of novel microsatellite loci in Orchesella villosa (Arthropoda, Collembola). | IRIS Università degli Studi di SienaIsolation of novel microsatellite loci in Orchesella villosa (Arthropoda, Collembola). | IRIS Università degli Studi di Siena
An experimental procedure using biotin-labelled probes and streptavidin-bound magnetic beads (FIASCO) was used to produce a microsatellite-enriched library for the collembolan Orchesella villosa. PCR primers were successfully constructed for seven loci containing, respectively, five pure, one interrupted, and one compound dinucleotide microsatellite repeats. As a preliminary test of their variability, we investigated 15 individuals from 5 locations inside a dismissed mining area in southern Tuscany. All microsatellite loci showed high levels of polymorphism. The mean number of different alleles at each locus across populations was 10.1 and observed heterozygosity per locus was 0.13-0.86. Only 2 out of the 7 loci appeared to be in Hardy-Weinberg equilibrium. The potential application of these loci to test the effects of environmental contamination on the genetic structure of exposed populations is discussed.. ...

Hemocyanin - WikipediaHemocyanin - Wikipedia
Hemocyanins (also spelled haemocyanins and abbreviated Hc) are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Oxygenation causes a color change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form. Hemocyanins are found only in the Mollusca and Arthropoda: the earliest discoveries of hemocyanins were in the snail Helix pomatia (a mollusc) and in the horseshoe crab (an arthropod). They were subsequently found to be common among crustaceans and are utilized by some land arthropods such as the tarantula Eurypelma californicum, the emperor scorpion, and the centipede Scutigera coleoptrata. Also, ...

Real Monstrosities: House CentipedeReal Monstrosities: House Centipede
I recently moved into a small studio an an historic building (old!) and there have been quite a few centipede visitors in the night. I dont seem to be able to catch them so I end up just chasing them away. One afternoon when I came home from work I noticed both my cats were in the bathtub playing with a huge centipede. I use the word playing deliberately because I stood and watched the three of them silently for about a minute, and was amazed at how unafraid the insect was of the two mammals. It just waddled around as though it were teasing the cats. Finally I yelled, Hey! and stomped my foot. The cats froze to look at me and the centipede zipped down the drain as fast as lightning. Very curious. It was as if it knew I was dangerous, and the cats were not. ...

The House Centipide Scutigera coleoptrata Xini Ta`l-Indewwa is unfortunately a well considered pest locally. Originally endemic to the Mediterranean region, the species has spread to other parts of the world, where it usually lives in human homes. This species can live its entire life inside a building, usually the ground levels of homes. They are generally considered harmless to humans. Bites are not common, and the jaws of most house centipedes are not strong enough to penetrate human skin . the latter feed on spiders, bedbugs, termites, cockroaches, silverfish, ants, and other household arthropods. They administer venom through modified legs. These are not part of their mandibles, so strictly speaking they sting rather than bite. They are mostly nocturnal hunters. Despite their developed eyes they seem to rely mostly on their antennae when hunting. Their antennae are sensitive to both smells and tactile information. They use both their mandibles and their legs for holding prey. This way they ...

Soil organic matter (SOM) cycling has significant consequences for ecosystem processes and functioning. Studies of SOM have focused traditionally on soil microorganisms that regulate the fundamental biochemical processes of litter mineralization and organic matter formation. However, microbe-mediated processes rarely occur in isolation in natural systems without the involvement of soil fauna. Nevertheless, little attention has been paid to soil fauna - e.g., the direct roles they play in SOM cycling, and indirect roles through changing microbial community composition, activity, and function to influence soil C and N dynamics. We combine traditional morphological characterization of soil invertebrates with microbial functional assays, and modern chemical techniques to identify relationships among soil fauna, microbe, plant residue inputs, and SOM. Our ultimate goal is to investigate whether/how soil fauna contribute to soil organic carbon storage, especially through their impacts on microbial ...

Abstract. Thousands of arthropod species, ranging from arachnids (spiders and scorpions) to hymenopterans (ants, bees, and wasps) and myriapods (centipedes), are venomous and use their venoms for both defense and predation. These venoms are invariably harmful to humans, and some may cause serious injuries, e.g., those from scorpions, spiders, and wasps. Arthropods venoms are also known as rich sources of biologically active compounds and have attracted the attention of toxin researchers for years. In this century, venom component analysis has progressed considerable due to the advances in analytical techniques, in particular, mass spectrometry and next-generation deep (DNA and RNA) sequencing. As such, proteomic and peptidomic analyses using LC-MS have enabled the full analysis of venom components, revealing a variety of novel peptide and protein toxins sequences and scaffolds, potentially useful as pharmacological research tools and for the development of highly selective peptide ligands and ...

The Crustacea are a subphylum of arthropods with 67,000 described species. They are part of the phylum Arthropoda. Crustaceans include crabs, lobsters, crayfish, shrimp, krill and barnacles. They are relatives of insects. If the Arthropods are regarded as a superphylum, then the insects and crustacea would be phyla. (see List of animal phyla). The group has an extensive fossil record, reaching back to the Cambrian. Most crustaceans are aquatic, mostly marine. Some have moved onto land permanently. Crustaceans that live on land include some crabs, and woodlice. Crustacea range in size from a parasite 0.1mm long, to the Japanese spider crab with a leg span of up to 14 ft (4.3 m) and a mass of 44 lb (20 kg). The North Atlantic lobster can weigh more than 40 pounds. Most crustaceans are mobile, but some become sessile after their larval stage. Barnacles become attached to rocks on the sea shore. Some are parasitic, like fish lice, and tongue worms. Crustacea usually have separate sexes, and the eggs ...

Arthropod pest control for UK oilseed rape - comparing insecticide efficacies, side effects and alternativesArthropod pest control for UK oilseed rape - comparing insecticide efficacies, side effects and alternatives
Oilseed rape (Brassica napus) is an important combinable break crop in the UK, which is largely protected from arthropod pests by insecticidal chemicals. Despite ongoing debate regarding the use of neonicotinoids, the dominant seed treatment ingredients used for this crop, there is little publicly available data comparing the efficacy of insecticides in controlling key arthropod pests or comparing the impacts on non-target species and the wider environment. To provide an insight into these matters, a UK-wide expert survey targeting agronomists and entomologists was conducted from March to June 2015. Based on the opinions of 90 respondents, an average of 20% yield loss caused by the key arthropod pests was expected to have occurred in the absence of insecticide treatments. Relatively older chemical groups were perceived to have lower efficacy for target pests than newer ones, partly due to the development of insecticide resistance. Without neonicotinoid seed treatments, a lack of good ...

Vaccines against Arthropods | The American Journal of Tropical Medicine and HygieneVaccines against Arthropods | The American Journal of Tropical Medicine and Hygiene
Abstract The possibility of vaccinating hosts against blood-feeding arthropods using antigens derived from salivary gland, gut, and other tissues is reviewed. These vaccines directed against vector arthropods also have the potential to effect the arthropods capacity to transmit pathogens, and this is distinct from transmission-blocking vaccines that use antigens derived from pathogens. Antigen extracts have been used in attempts to vaccinate against fleas, lice, keds, flies, mosquitoes, and a number of tick species. A vaccine against the cattle tick, Boophilus microplus (Canestrini), using a recombinant antigen, has been tested under field conditions. Ticks feeding on vaccinated hosts are damaged by an immune response directed against their gut cells. Some die on the host, others engore but their fecundity is reduced. The Commonwealth Scientific Industrial Research Organization-Biotechnology Australia tick vaccine against B. microplus is cited as a model for the development of other vaccines. It is

Maxillopoda. Ostracoda. Malacostraca. Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae.. Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which ...

Global Malaise Program | Centre for Biodiversity GenomicsGlobal Malaise Program | Centre for Biodiversity Genomics
CBG provides a standard sampling kit to all GMP participants. This includes a brand new Townes style Malaise trap and typically a years worth of collection bottles. Partners provide ethanol for killing and preserving samples and are responsible for changing the collection bottle once every week for the duration of the flight season.. All collection bottles are shipped for subsequent processing at CBG. Samples are accessioned, specimens were identified to order, arrayed, labeled, databased, and tissue-sampled for genetic analysis. All arthropods are barcoded, with the exception of a few very common species of Collembola, where only a few individuals from each trap sample were analyzed. Standard barcoding protocols are followed to recover the barcode region of cytochrome c oxidase subunit I (COI) gene. The barcode sequences, specimen images and collateral data are uploaded to BOLD under the Global Malaise Program campaign. Barcoded specimens are assigned to an existing or new Barcode Index ...

Frontiers | Bee Viruses: Routes of Infection in Hymenoptera | MicrobiologyFrontiers | Bee Viruses: Routes of Infection in Hymenoptera | Microbiology
Numerous studies have recently reported on the discovery of bee viruses in different arthropod species and their possible transmission routes, vastly increasing our understanding of these viruses and their distribution. Here, we review the current literature on the recent advances in understanding the transmission of viruses, both on the presence of bee viruses in Apis and non-Apis bee species and on the discovery of previously unknown bee viruses. The natural transmission of bee viruses will be discussed among different bee species and other insects. Finally, the research potential of in vivo (host organisms) and in vitro (cell lines) serial passages of bee viruses is discussed, from the perspective of the host-virus landscape changes and potential transmission routes for emerging bee virus infections.

Insects, Class Hexapoda (meaning six-footed), has the largest number of species within this phylum. In addition to the characteristics already mentioned, insects also are distinguished by having one pair of antennae, and most have wings and three body regions as adults. Centipedes, millipedes, mites, sowbugs, and spiders are non-insect arthropods: all have external skeletons but adults have more than six legs. Insects are by far

Selecting PesticidesSelecting Pesticides
When choosing a pesticide, the landscaper should select a product that is specific to the pest to be controlled in order to spare beneficial arthropods. Systemic insecticides are less likely to affect predators and parasites on plant surfaces. Insecticidal soaps may spare hard bodied predaceous or parasitic arthropods. Microbial insecticides such as Bacillus thuringiensis products (Dipel®, Thuricide® and others) are target-specific for certain groups of insects. Specific miticides generally spare other arthropods.. Care must also be taken when using pesticides other than insecticides and miticides. Certain fungicides such as Benlate® will affect insectivorous fungi and other non-target organisms. Broad-spectrum insecticides often are useful when more than one pest is present, but they may cause a rapid resurgence of the primary or secondary pest. Pyrethroid insecticides can be more harmful to parasitic wasps than to the pests listed on their labels and may result in secondary pest outbreaks. ...

The European Union (EU) is facing the recent arrival of the bacterium Xylella fastidiosa. Its fast spread has caused great alarm because of the economic impact it implies for the agroeconomy of European countries. Among its insect vectors, Philaenus spumarius has been demonstrated to transmit the bacterium from infected to uninfected trees in the EU, where different measures have been established to control it. One of the proposals to manage this vector is the augmentation of natural enemy populations. However, the identification of candidate predator species is essential if such a management system is to be introduced. The present paper describes a set of species-specific primers designed to detect the presence of P. spumarius DNA in soil arthropod fauna generalist predators’ gut which can reveal candidate species for the pest’s biological control. Such primers have been proven to be a useful and reliable taxonomic tool for P. spumarius identification at any life stage, i.e., nymphs. This

Change Over Time | manoa.hawaii.edu/ExploringOurFluidEarthChange Over Time | manoa.hawaii.edu/ExploringOurFluidEarth
The Paleozoic era spanned from 540 to 252 million years ago (mya) and represents the first era of diverse, complex life on Earth. The name Paleozoic means ancient life. During the early Paleozoic era, many new groups of marine invertebrates (animals without backbones) dominated the earth, although primitive vertebrates (animals with backbones) also began to appear. As the Cambrian explosion continued, almost all of the major groups of modern animals evolved from shared common ancestors. The ancient world ocean brimmed with invertebrate animals such as sponges, corals, and crabs (Fig. 7.11 A) as well as the first vertebrate animals: fishes (Fig. 7.11 B). The first animals to begin to colonize dry land were likely arthropods (Fig. 7.11 C). Arthropods are a group of invertebrate animals with jointed arms and hard shells including crabs, shrimp, spiders, and insects. By the end of the Paleozoic era-almost 300 mya after the Cambrian explosion-arthropods, amphibians, and some primitive reptiles ...

Morphological and Functional Diversity of Ant Mandibles - AntWikiMorphological and Functional Diversity of Ant Mandibles - AntWiki
Mandibles are also crucial to the hunting success of predatory ants. Mandibles can be wielded as formidable weapons in their own right, or as tools with which to grasp prey until a paralyzing sting can be delivered (a common strategy in the Ponerinae, most of which are solitary predators). Mass foraging predators (e.g. army ants, described below) use their mandibles to pin down prey from all sides while their nestmates dispatch it. A number of highly modified mandibles have evolved in response to the requirements of catching certain prey, especially those that are otherwise difficult to catch (e.g. collembolans). See the section on specialized predators below for several examples of such modifications. Despite a common misconception, most ants lack painful bites (being too small to have any effect on human skin). Usually ant bites are actually the venomous stings of ants in certain subfamilies (most commonly the Myrmicinae, but also members of the Ponerinae, Myrmeciinae, Pseudomyrmecinae, and ...

Spiracle (arthropods)Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects and some spiders to allow air to enter the trachea. In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle. In order to open, the muscle relaxes. The closer muscle is controlled by the central nervous system, but can also react to localized chemical stimuli. Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. The timing and duration of spiracle closures can affect the respiratory rates of the organism. Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss. Although all insects have spiracles, only some spiders have them, such as orb weavers and wolf spiders. Ancestrally, spiders have book ...

Palaeos Arthropods: Crustacea: MalacostracaPalaeos Arthropods: Crustacea: Malacostraca
The following is from Wikipedia. To save time, refernces have not been hyperlinked. The class Malacostraca is united by a number of well-defined and documented features, which were recognised a century ago by William Thomas Calman, who in 1904 ,[1] and 1909 described these common morphological features and introduced the major taxonomic subdivisions of the Malacostraca which are still in use today: he divided the Malacostraca in two subclasses the Phyllocarida and the Eumalacostraca, which is further subdivided into four superorders: Eucarida, Peracarida, Hoplocarida and Syncarida.[8] Calman coined the term caridoid facies for the common eumalacostracan (shrimp-like) features; the most important of these is the constant number of segments in each tagma: members of this class have five segments in the cephalon, eight thoracic segments (thoracomeres) and six segments in the pleon and possess a telson, which forms a characteristic tail fan when the uropods are present. Many other characteristic ...

Insects and arthropods3
  • There are bees, other insects and arthropods, some fungi, and even a few mysteries. (smokiesinformation.org)
  • The similarities between their locomotive strategy and that of much larger insects and arthropods opens up several very interesting evolutionary questions," Nirody says. (cosmosmagazine.com)
  • The journal publishes re- views, research papers, and communications related to the biology, physiology, and behavior of insects and arthropods. (bvs.br)
Species26
  • To my knowledge, this is not only the largest terrestrial trackway of a walking arthropod to be found so far, but is also the first record of locomotion on land for a species of Hibbertopterus (Eurypterida). (nature.com)
  • This paper presents new records, range extensions, and a checklist of arthropod species found associated with the most common and widespread native tree in the Hawaiian Islands, 'öhi'a lehua (Myrtaceae: Metrosideros polymorpha Gaudichaud-Beaupré). (umd.edu)
  • Together, they were part of the largest ever systematic attempt to answer a disarmingly simple question: in a patch of tropical rainforest, how many species of insects and other arthropods are there? (discovermagazine.com)
  • Using computer simulations to scale that up, they estimate that the entire 6,000-hectare Manhattan-sized forest is home to around 25,000 arthropod species. (discovermagazine.com)
  • It's the first solid estimate of its kind, and it reveals a surprising trend: every hectare of the forest contains almost two-thirds (64 percent) of all the arthropod species in the whole area. (discovermagazine.com)
  • Methods Arthropod and bird abundances were sampled across the study area and analysed using hierarchical joint species distribution models (JSDMs). (tu-berlin.de)
  • and the nature group (36 species) were positively related to arthropod abundance, but the species abundance decreased sharply with increasing anthropogenic disturbance. (tu-berlin.de)
  • Main conclusions Arthropod abundance clearly modulated birds' responses to the urbanization gradient for most species. (tu-berlin.de)
  • Especially at moderate levels of anthropogenic disturbance, the abundance of arthropods is key for the occurrence and abundance of bird species in urban areas. (tu-berlin.de)
  • In the most comprehensive and thorough survey of its kind, an international team of scientists sampled, sorted and cataloged every arthropod species they could find in patches of Panama's San Lorenzo rainforest . (zmescience.com)
  • During their survey of areas summing up to roughly three acres, the scientists estimated that a 6,000 hectare forest houses 25,000 arthropod species, 60% to 70% of which are likely to be previously unknown. (zmescience.com)
  • The next 8 years were spent by the researchers identifying and cataloging the arthropod species. (zmescience.com)
  • It's worth mentioning that the arthropod family houses the most multicellular species. (zmescience.com)
  • Practically, for every mammal species, there are 300 arthropod species that live in the rainforest alone. (zmescience.com)
  • Some 0.48 hectares in combined surface were directly studied, where 6144 arthropod species were identified. (zmescience.com)
  • By scaling up diversity values and extrapolating their known data, the researchers estimated the rainforest reserve harbors in excess of 25,000 arthropod species. (zmescience.com)
  • This is good news, as it means that to determine the species diversity of a tropical rainforest, we need not sample gigantic areas: a total of one hectare may suffice to get an idea of regional arthropod richness - provided that this total includes widely spaced plots representative of variation within the forest," said Roslin. (zmescience.com)
  • The scientists found a link between the number of arthropod species and the richness of plant diversity in the area. (zmescience.com)
  • A new study on the interactions of microplastics and chemicals on soil arthropods reveals that the effects are dependent on the type of microplastic and the exposed arthropod species. (miljo.fi)
  • The researchers aimed at finding out how the co-exposure with microplastics alters the effects of chlorpyrifos on soil arthropods, and whether the effects are dependent on the type of microplastic and the exposed arthropod species. (miljo.fi)
  • In general, arthropods either showed no pronounced seasonal peak in abundance, or a summer peak, although these patterns differed between habitat components within species, and between species. (up.ac.za)
  • Quantitative analyses highlighted prominent differences between the two habitat components in arthropod community structure, despite the fact that most species were common to both of them. (up.ac.za)
  • Chapters cover such topics as arthropods as food for humans, arthropods as a bioindicator species, use of arthropods in the cosmetic and pharmaceutical industries, arthropods and their conservation status, diets for raising arthropods, and much more. (doabooks.org)
  • On the other hand, if arthropods and tardigrades converged upon this strategy independently, then there's much to be said about what makes this strategy so palatable for species in different environments. (cosmosmagazine.com)
  • Understanding how plant species richness influences the diversity of herbivorous and predatory/parasitic arthropods is central to community ecology. (sun.ac.za)
  • Interestingly, several species including one trematode, one nematode and four arthropods generated FABP mRNA variants via alternative splicing. (nottingham.ac.uk)

Parasites1
  • Among them are ticks, which are small bloodsucking parasites and arthropods. (medlineplus.gov)
Mosquitoes3
  • Blood - feeding arthropods , such as mosquitoes and ticks , can harbour a variety of viral pathogens that can cause infectious diseases in both human and animal hosts. (bvsalud.org)
  • In this review , we discuss the arthropod immune response to viral infections with a primary focus on the innate immune responses of ticks and mosquitoes . (bvsalud.org)
  • Zika virus is an arthropod-borne flavivirus, which is transmitted primarily by mosquitoes of the Aedes genus, but can also be transmitted through sexual intercourse. (bvsalud.org)
Toxicity to soil2
  • The article "Modulation of chlorpyrifos toxicity to soil arthropods by simultaneous exposure to polyester microfibers or tire particle microplastics" was published in Applied Soil Ecology on the 15 September 2022. (miljo.fi)

Extinct1
  • Look at, learn about and colour 17 extinct arthropods in this book! (nhbs.com)
Exoskeleton3
  • There are many functions of the arthropod exoskeleton. (earthlife.net)
  • Despite comprising the same fibrous compound found in other arthropods, chitin, the thin exoskeleton of a fly does not provide the same protection. (earthlife.net)
  • Some of these released substances are caustic and can burn the exoskeleton of other arthropods or cause skin and mucous inflammation in bigger animals. (wordpress.com)
Middle Cambrian5
  • An extensive cladistic analysis resolved Kootenichela as sister-taxon to the enigmatic Worthenella cambria from the middle Cambrian (Series 3, Stage 5), Burgess Shale Formation in Yoho National Park (British Columbia), which is herein reinterpreted as a megacheiran arthropod. (bioone.org)

  • This illustration shows some of the general characteristics of arthropods. (medlineplus.gov)
  • The effectiveness of rehabilitation efforts was assessed relative to arthropod richness, vegetation and arthropod community composition, and ground-cover characteristics in 3 habitats: undisturbed, burned and weed infested ( B. tectorum ), and burned then rehabilitated with native and nonnative vegetation. (byu.edu)
  • Nonmetric multidimensional scaling and nonparametric multivariate statistical procedures, including analysis of similarity and similarity percentage routines, were used to compare arthropod and vegetation community composition and ground-cover characteristics between habitats. (byu.edu)
  • Arthropod richness, arthropod and vegetation community composition, and ground-cover characteristics were all useful indicators but returned slightly different results. (byu.edu)
Invertebrate1

Small mammals1
  • There was no significant effect of buffer width or time since buffer establishment on the size of the difference in abundance between buffers and unharvested sites (amphibians, birds, small mammals and arthropods combined). (conservationevidence.com)
Anthropogenic2
  • Quantitative studies of complete soil arthropod communities are considered essential if a thorough understanding of the structure and dynamics of soil faunas, and their likely response to anthropogenic environmental change, is to be gained. (up.ac.za)
  • It is concluded that quantitative analyses of soil arthropod communities are essential if natural and anthropogenic changes in their structure are to be detected, monitored and understood. (up.ac.za)
Mammals1
  • After talking about venomous mammals , fishes and lizards , 'All you need is Biology' brings you this post about venomous and poisonous arthropods. (wordpress.com)
Richness1
  • Differences in arthropod richness were compared using rarefaction curves. (byu.edu)
Soil2
  • Most studies on the interactions of microplastics and chemicals have focused on aquatic environments and only a few addressed soil arthropods. (miljo.fi)
  • Soil arthropod communities in these two distinct habitat components were quantified over one year. (up.ac.za)
Called pitfall1
  • The CAP LTER has been collecting arthropods since 1998 using a simple but effective technique called pitfall trapping that entails capturing organisms that fall into plastic cups buried in the ground. (asu.edu)
Viral1
  • We aim to summarize critically the vector immune system and their infection transmission strategies to mammalian hosts to foster debate that could help in developing new therapeutic strategies to protect human and animal hosts against arthropod -borne viral infections . (bvsalud.org)
Herbivorous1
  • Another exciting finding was that the diversity of both herbivorous and non-herbivorous arthropods could be accurately predicted from the diversity of plants", says Basset. (zmescience.com)
Venomous2
  • Venomous and poisonous arthropods: what makes them different? (wordpress.com)
  • The most distal part of the scorpion tail, the telson (an additional segment found in several arthropods), has become a venomous organ that ends in a stinger . (wordpress.com)
Scorpions1
  • There are several groups of Lower Carboniferous (Asbian) arthropods that might have been capable of leaving large trackways 1 , but only the water scorpions, or eurypterids 1 , are likely to have left the trackway described here. (nature.com)
Birds1
  • Metrosideros also provides important habitat for birds that forage for arthropod prey in the foliage (e.g., 'akepa [Loxops coccineus]) and bark (e.g. (umd.edu)
